Specification forming part of Letters Paton To all "whom it may concern Be it known that I, EDWARD FrrzHENRv, of Soinerville, in the county of Middlesex, and in the State of Massachusetts, have invented certain new and useful Improvements in Leather-Dressing Machine; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

My present invention is intended as an improvement on the hide-and-leather-working machine for which Letters Patent Nos. 125,276 and 156,991 were granted to me, respectively, April 2, 1872, and November 17,1874; and it consists in the construction and-arrangement of the devices for raising and lowering the tools, and for starting and stopping the same to and from the work, as will be hereinafter more full y set forth.

In order to enable others skilled in the art and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a side elevation of the steam cylinder and carriage embodying my invention. Fig. 2 is a partial longitudinal section of the same. Fig. 3 is a transverse vertical tached" parts of the machine.

A represents the steam-cylinder provided on its sides with the grooved ways a, in which the frame or carriage'B is moved back and forth by the piston-rod b'passing through both ends of the cylinder, as shown and described in my former patents above referred to. Inthe lower portion of the frame or car riage B at each end is a rocking shaft, d, with arms 0 e projecting outward therefrom, and to the outer ends of said. arms the toolholder 0 is secured. D is the. tool, and E the covering-plate, which are fastened to the toolholder by screws ff passing through them. From the back of each'rockin g shaft (1 extends an arm, h, which is curved upward, as shown, and the upper portion slotted or forked and pivoted-to a slide, G. This slide or sleeve is placed loosely on a bar, H, to each end of which are pivoted two links, i i. Thelinks at one end of the bar H are placed loosely on a shaft, m, while the links at the other end are secured to a similar shaft, m. The two bars H H with'their links are so arranged that Letters Patent, is

ends of a shaft, a, above the cylinderA in the center. On this shaft are secured two cams,

p 19, each of which operates a lever, L, pivoted in a slotted bar, P, placed in the frame-work connected to the cylinder. Thelower ends of the levers L L are, by bars or' rods R R, connected with cranks s s on the shafts m mthat is, one lever connects with one shaft, and the other lever with the other shaft.

When the machine is in operation the shafts m mare rocked by means of the cams p, levers L, connectingbars R, and cranks 8, whereby the bars H are moved lengthwise, and alternately-raised and lowered, thereby alternately raising and lowering the tools.

S is the hand-wheel for swinging the entire mechanism in any direction. On the under side of this wheel are two rods, t t, each. of which connects with hinged levers V V carrying a wedge, W. These wedges are pushed down in grooves at the ends of.the fulcrunr bars P P to hold them stationary while the machine is in operation. To stop the tools it is only necessary to push the rods 25 inward, when the wedges will be drawn and the bars or boxes P become movable, thereby removing the fulcrums of the levers L so that they will not operate. The wedges W are guided in their up and down movement by means of pins 00 m.

Having thus fully described my invention, what I claim as new, and desire to secure by 1. The combination of the cam 10, lever L, connecting-bar R, crank .9, bar H with links i,-slide G, and arm h, connected to the rocking tool-holder, substantially as and for the purposes herein set forth. I

2. The combination of the lever L, fulcrum bar or box P, wedge W, levers V, and rod t,

substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set in day of May, 1876.
